Water Desalination Equipment Industry

The global market for water desalination equipment was valued at approximately USD 18.36 billion in 2024 and is expected to experience a significant growth rate, with a compound annual growth rate (CAGR) of 9.6% projected between 2025 and 2030. This growth is driven primarily by the increasing scarcity of freshwater resources combined with the rising demand for water across many arid and semi-arid regions around the world. These regions typically lack natural surface water sources such as lakes, rivers, or reservoirs, which has led to a growing need for water desalination technologies and equipment on a global scale.

Data from the World Economic Forum highlights that by the year 2030, global demand for freshwater is expected to surpass available supply by as much as 40%, resulting in approximately 1.6 billion people facing a lack of access to safely managed drinking water. At present, nearly 4 billion individuals reside in regions classified as water-scarce, while one out of every four urban areas worldwide is currently experiencing issues related to water insecurity.

As the challenge of water scarcity continues to intensify, the demand for efficient and effective desalination equipment is rapidly increasing, as these technologies are essential in closing the growing gap between water supply and demand. Water is an indispensable resource that is vital not only for everyday life but also plays a crucial role in various industrial processes and construction activities. According to information provided by the U.S. Geological Survey (USGS), about 71% of the Earth’s surface is covered by water, but of this total, an overwhelming 96.5% consists of saline water found in oceans, seas, and bays. Only a small fraction, approximately 3.5%, constitutes freshwater, which is sourced from groundwater reserves, rivers, streams, and lakes. This limited freshwater availability underscores the importance of its sustainable management to meet both human consumption needs and industrial requirements.
